风险控制对众包创新模式有效性的杠杆作用研究

随着"互联网+"在各个领域的广泛应用,众包创新平台应运而生。众包创新作为协同创新的一种模式,基于互联网平台为企业提供创新服务,可以有效提升企业核心竞争力。基于风险感知理论与风险控制相关文献,从平台风险控制角度,以猪八戒众包创新平台为例,采用数据挖掘技术获取平台一手数据,利用层次回归模型研究风险控制机制对众包创新平台有效性的影响。研究发现:通过建立接包方服务绩效评价体系与平台功能风险控制(保证金及接包商信誉评级)可以降低发包方对众包创新的感知风险,从而增强众包创新平台有效性。在两种风险控制机制的交互作用下,平台的有效性会得到进一步提升。此结论有助于众包创新平台运营及服务监管,促进平台交易环境向正规化、有序化方向发展,提升平台竞争力。     

政府补贴下竞争型WEEE闭环供应链定价决策研究

针对由单个制造商和两个回收商组成的电子电器闭环供应链,考虑合格回收商与不合格回收商相互竞争,研究政府回收处理补贴及消费者渠道偏好对闭环供应链决策的影响。发现:竞争环境下,随着回收处理补贴的提高,合格回收商的竞争力随之增大;制造商、各回收商及系统利润均随着消费者对正规回收渠道偏好的提高而增加,政府应积极促进消费者对正规回收渠道的认知与接受度。     

社会责任信息披露与产品市场竞争 对权益资本成本的影响研究

为研究社会责任信息披露与产品市场竞争对权益资本成本的影响,选取2014—2017年沪深A股上市公司数据进行实证分析。结果表明,企业社会责任信息披露与产品市场竞争都能降低权益资本成本;产品市场竞争的激烈程度影响社会责任信息披露与权益资本成本之间的关系,产品市场竞争越激烈,社会责任信息披露降低权益资本成本效果越明显;上述变量特征关系在非国有企业中比在国有企业中更加显著。根据研究结果,对企业与相关监管机构提出建议：企业应更加注重内外部治理机制的协调发展,在不断提升社会责任信息披露质量的同时,完善自身市场竞争机制,以达到降低权益资本成本的目的;监管机构应加强社会责任信息披露立法,规范我国资本市场发展。     

银行业竞争对企业投资效率的影响——基于债务治理与融资约束的双重视角

在全面加快金融供给侧结构性改革背景下,推动银行业竞争是促进金融服务实体经济发展、提升企业投资效率的重要途径之一。基于手动收集的中国各省区商业银行分支机构数据,结合中国上市企业财务数据,考察银行业竞争对企业投资效率产生的影响。研究发现:尽管银行业竞争显著地增加了企业投资水平,但是并未对企业投资效率产生直接的影响。进一步地,银行业竞争虽然通过减少融资约束和加强债务治理来缓解国有企业投资不足行为,但是融资作用的发挥也可能会加剧国有企业过度投资,因而银行业竞争对国有企业投资效率将取决于投资不足和过度投资的相对程度。同时,银行业竞争通过加强债务治理作用抑制非国有企业的过度投资,也通过缓解融资约束问题来减弱非国有企业的投资不足问题,进而共同促进非国有企业投资效率的提高。     

我国非司法ODR的适用与完善——以闲鱼小法庭为例

互联网经济纠纷的急速增长,迫切需要我国加强完善线上纠纷解决机制(ODR)以解决网络空间中的权利冲突问题。非司法ODR既传承了我国儒家传统的无讼解纷思想,又融会了前沿领域的互联网信息技术,充分将传统与现代相结合并创新智造出具有“线上纠纷线上解决”属性的诉源治理新模式。以闲鱼小法庭为例,基于个人、组织、社会三维效益论视角分析发现:非司法ODR通过融合非诉解纷理念能够实现形式多元、信息互通、对抗性弱的私力救济;非司法ODR通过倡导诉前分流机制可以实现缓解诉讼压力、降低诉讼延迟、优化司法资源配置;非司法ODR通过发挥定分止争作用真正实现了社会整体的非诉福祉建设。为了加快推动具有民间性、自治性、高效性的非司法ODR成为化解涉网纠纷的第一道防线,建议通过国家立法确认其正当地位,建立与司法ODR的衔接机制,规范解纷人员的职业操守,健全对网民数据的隐私保护机制,建立非司法ODR的司法确认制度。      

从话语权看中国特色大国外交话语的建构原则

中国特色大国外交话语体系的建构需要考虑多元文化之间的话语权竞争,结合话语传播中要素资源的利用来确定基本原则。这要求我们克服西方二元对立的话语权力观,树立社会建构主义的辩证话语权力观。我们需要挖掘中国优秀传统文化,融合其他民族的优秀文化,建立科学的中国特色外交话语理论体系,适时提出中国话题和中国方案,增强我国的内容掌控权。在参与者上,除传统外交中的政府机构和人员外,还需要组织调动各种非政府组织、企业、机构、个人参与公共外交话语活动,利用通俗方式对外方的普通民众进行潜移默化的宣传解释。在平台上,在加强对传统媒介资源的利用之外,还要充分调动书刊、影视、广告、自媒体等大众传媒手段,增强我国的媒体控制权。这些原则须置于整体外交话语体系之中,保证我国外交话语体系的建构有助于增强我国的外交话语权。     

基于电商平台的制造商合约与销售服务模式选择策略研究

NEIGHBOUR ANALYSIS WITH ADJUSTMENT FOR INTERPLOT COMPETITION

In field experiments involving a large number of experimental plots, a neighbour analysis can be used to control environmental variation by estimating the trend within blocks. The effect of interplot competition is another important source of variation which has an influence on the estimation of treatment contrasts. To reduce the effect of the variation from these sources and to improve the precision of comparison between treatments, a spatial model is proposed for incorporating both trend effect and interplot competition. It is a modification to the residual maximum likelihood neighbour analysis of Gleeson & Cullis (1987) using the two neighbouring treatment effects to estimate interplot competition. A real example is used to illustrate this methodology. The results indicate that the extended model gives no appreciable difference in standard error of mean differences compared with the model taking into account the trend effect only. However, the rankings of estimated treatment means do differ. More research using both real and simulated data is required before such models that incorporate trend and competition effects can be confidently recommended.     

The Effect of Gender Context on Children's Social Behavior in a Limited Resource Situation: An Observational Study

Knowing when to compete and when to cooperate to maximize opportunities for equal access to activities and materials in groups is critical to children's social and cognitive development. The present study examined the individual (gender, social competence) and contextual factors (gender context) that may determine why some children are more successful than others. One hundred and fifty‐six children (M age=6.5 years) were divided into 39 groups of four and videotaped while engaged in a task that required them to cooperate in order to view cartoons. Children within all groups were unfamiliar to one another. Groups varied in gender composition (all girls, all boys, or mixed‐sex) and social competence (high vs. low). Group composition by gender interaction effects were found. Girls were most successful at gaining viewing time in same‐sex groups, and least successful in mixed‐sex groups. Conversely, boys were least successful in same‐sex groups and most successful in mixed‐sex groups. Similar results were also found at the group level of analysis; however, the way in which the resources were distributed differed as a function of group type. Same‐sex girl groups were inequitable but efficient whereas same‐sex boy groups were more equitable than mixed groups but inefficient compared to same‐sex girl groups. Social competence did not influence children's behavior. The findings from the present study highlight the effect of gender context on cooperation and competition and the relevance of adopting an unfamiliar peer paradigm when investigating children's social behavior.
